FIELD OF THE INVENTION

The present invention relates to novel heterocyclic compounds useful as inhibitors of ERK1 and ERK2. The present invention further relates to compositions containing such compounds, and methods of use thereof.

BACKGROUND OF THE INVENTION

ERK1 and ERK2 (collectively “ERK1/2”) are related protein-serine/threonine kinases that participate in, amongst others, the Ras-Raf-MEK-ERK signal transduction pathway, which is sometimes denoted as the mitogen-activated protein kinase (MAPK) pathway. This pathway is thought to play a central role in regulating a number of fundamental cellular processes including one or more of cell proliferation, survival, adhesion, cycle progression, migration, differentiation, metabolism, and transcription. The activation of the MAPK pathway has been reported in numerous tumor types including lung, colon, pancreatic, renal, and ovarian cancers. Accordingly, substances that could reduce activation could be of interest for possible treatments.

ERK1/2 appear to be activated by MEK through phosphorylation of both a threonine and a tyrosine residue, namely at Tyr204/187 and Thr202/185. Once activated, ERK1/2 catalyze the phosphorylation of serine/threonine residues of more than 100 substrates and activate both cytosolic and nuclear proteins that are linked to cell growth, proliferation, survival, angiogenesis and differentiation, all hallmarks of the cancer phenotype. Thus it may be beneficial to target ERK to develop and use ERK1/2 inhibitors as a way to inhibit tumor growth.

Furthermore, an ERK inhibitor may have utility in combination with other MAPK inhibitors. Recently, researchers reported that dual inhibition of MEK and ERK by small molecule inhibitors was synergistic and acted to overcome acquired resistance to MEK inhibitors. See Hatzivassiliou et al., ERK Inhibition Overcomes Acquired Resistance to MEK Inhibition, Mol. Cancer Ther. 2012, 11, 1143-1154.

Small molecular ERK inhibitors have been reported in the literature including U.S. Pat. Nos. 6,743,941, 8,546,404, and Ren et al., Discovery of Highly Potent, Selective and Efficacious Small Molecule Inhibitors of ERK1/2, J. Med. Chem., 2015, 58(4), 1976-1991. A small number of ERK inhibitors (e.g., BVD-523 and GDC-0994) are in early clinical development. However, no ERK inhibitor has been reported to advance into late stage clinical trials. Therefore, there is a continuing need for the development of improved and efficacious ERK1/2 inhibitors for the treatment of cancer.

Prodrugs of compounds of formulae (I-III) may be used to modulate the pharmacokinetic properties, using various methods known to those skilled in the art. See, e.g., Jarkko Rautio et al., Nature Reviews Drug Discovery, 7:255-270 (2008), which is hereby incorporated by reference. In the case of drugs containing an amine moiety such as when R² is CH₂NH₂, a variety of prodrug approaches have been reviewed by A. L. Simplício, Molecules, 13:519-547 (2008), which is hereby incorporated by reference. More specifically, (alkoxycarbonyloxy)alkyl carbamates, (acyloxy)alkyl carbamates, and (oxodioxolenyl)alkyl carbamates have been reported as effective prodrug strategies for amines by Zhong Li, Bioorg. Med. Chem. Lett., 7:2909-2912 (1997); J. Alexander, J. Med. Chem., 34:78-81 (1991); J. Alexander, J. Med. Chem., 31:318-322 (1988); and J. Alexander, J. Med. Chem., 39:480-486 (1996), all of which are incorporated by reference herein. In one embodiment, the prodrug is an amide of formulae (I-III). In one embodiment, when R² is CH₂NH₂, the amide is

C(O)(C₁₋₆alkyl), wherein C₁₋₆alkyl can be optionally substituted. In another embodiment, the prodrug is an ester of formulae (I-III). In one embodiment, when R² is CH₂OH, the ester of it is

In a further embodiment, a compound of the invention may be a solvate. As used herein, “solvate” does not significantly alter the physiological activity or toxicity of the compounds, and as such may function as pharmacological equivalents to non-solvate compounds of the invention. The term “solvate” as used herein is a combination, physical association and/or solvation of a compound of the present invention with a solvent molecule. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances, the solvate can be isolated, such as when one or more solvent molecules are incorporated into the crystal lattice of a crystalline solid. Thus, “solvate” encompasses both solution-phase and isolatable solvates. A hydrate is a special form of solvate which includes water combined in a definite ratio as water of crystallization.

Compounds described herein may contain an asymmetric center and may thus exist as enantiomers. Where the compounds according to the invention possess two or more asymmetric centers, they may exist as diastereomers. When bonds to the chiral center are depicted as straight lines in the formula of the invention, it is understood that both the (R) and (S) configurations, and hence both enantiomers and mixtures thereof, are embraced. The present invention includes all such possible stereoisomers, unless the specific stereochemistry is specifically indicated. It is well known in the art how to prepare substantially pure stereoisomer, such as by resolution of racemic forms or by synthesis from optically active starting materials. In one embodiment, the compound of formulae (I-III) is a substantially pure stereoisomer. “Substantially pure stereoisomer” refers to a stereoisomer form is at least 95% pure with respect to other stereoisomers of otherwise the same structure.

The words “comprise”, “comprises”, and “comprising” are to be interpreted inclusively rather than exclusively. The words “consist”, “consisting”, and its variants, are to be interpreted exclusively, rather than inclusively.

As used herein, the term “about” means a variability of 10% from the reference given, unless otherwise specified.

A “patient” or “subject” is a mammal, e.g., a human or a veterinary patient or subject, e.g., mouse, rat, guinea pig, dog, cat, horse, cow, pig, or non-human primate, such as a monkey, chimpanzee, baboon or gorilla.

The term “treating” or “treatment” is meant to encompass administering to a subject a compound of the present invention for the purposes of amelioration of one or more symptoms of a disease or disorder, including palliative care. A “therapeutically effective amount” refers to the minimum amount of the active compound which effects treatment.

Pharmaceutical compositions useful herein contain at least one or more of compounds of formulae (I)-(III), or pharmaceutically acceptable salts, prodrugs, solvates, hydrates, or stereoisomers thereof in a pharmaceutically acceptable carrier optionally with other pharmaceutically inert or inactive ingredients. In another embodiment, a compound of formulae (I-III) is present in a single composition. In a further embodiment, a compound of formulae (I-III) is combined with one or more excipients and/or other therapeutic agents as described below.

The pharmaceutical compositions of the invention comprise an amount of at least one or more of compounds of formulae (I-III) or pharmaceutically acceptable salts, prodrugs, solvates, hydrates, or stereoisomers thereof that is effective for treating a condition treatable by inhibiting ERK1/2 in a subject in need thereof. Specifically, the dosage of the compound of formulae (I-III) to achieve a therapeutic effect will depend on the formulation, age, weight and sex of the patient and route of delivery. It is also contemplated that the treatment and dosage of the compound of formulae (I-III) may be administered in unit dosage form and that one skilled in the art would adjust the unit dosage form accordingly to reflect the relative level of activity. The decision as to the particular dosage to be employed (and the number of times to be administered per day) is within the discretion of the ordinarily-skilled physician, and may be varied by titration of the dosage to the particular circumstances to produce the desired therapeutic effect. In one embodiment, the therapeutically effective amount is about 0.01 mg/kg to 10 mg/kg body weight. In another embodiment, the therapeutically effective amount is less than about 5 g/kg, about 500 mg/kg, about 400 mg/kg, about 300 mg/kg, about 200 mg/kg, about 100 mg/kg, about 50 mg/kg, about 25 mg/kg, about 10 mg/kg, about 1 mg/kg, about 0.5 mg/kg, about 0.25 mg/kg, about 0.1 mg/kg, about 100 μg/kg, about 75 μg/kg, about 50 μg/kg, about 25 μg/kg, about 10 μg/kg, or about 1 μg/kg. However, the therapeutically effective amount of the compound of formulae (I-III) can be determined by the attending physician and depends on the condition treated, the compound administered, the route of delivery, the age, weight, severity of the patient's symptoms and response pattern of the patient.

The therapeutically effective amounts may be provided on regular schedule, i.e., daily, weekly, monthly, or yearly basis or on an irregular schedule with varying administration days, weeks, months, etc. Alternatively, the therapeutically effective amount to be administered may vary. In one embodiment, the therapeutically effective amount for the first dose is higher than the therapeutically effective amount for one or more of the subsequent doses. In another embodiment, the therapeutically effective amount for the first dose is lower than the therapeutically effective amount for one or more of the subsequent doses. Equivalent dosages may be administered over various time periods including, but not limited to, about every 2 hours, about every 6 hours, about every 8 hours, about every 12 hours, about every 24 hours, about every 36 hours, about every 48 hours, about every 72 hours, about every week, about every two weeks, about every three weeks, about every month, and about every two months. The number and frequency of dosages corresponding to a completed course of therapy will be determined according to the judgment of a health-care practitioner. The therapeutically effective amounts described herein refer to total amounts administered for a given time period; that is, if more than one compound of formulae (I-III) or a pharmaceutically acceptable salt, prodrug or solvate thereof is administered, the therapeutically effective amounts correspond to the total amount administered.

The pharmaceutical compositions containing a compound of formulae (I-III) may be formulated neat or with one or more pharmaceutical carriers for administration. The amount of the pharmaceutical carrier(s) is determined by the solubility and chemical nature of the compound of formulae (I-III), chosen route of administration and standard pharmacological practice. The pharmaceutical carrier(s) may be solid or liquid and may incorporate both solid and liquid carriers. A variety of suitable liquid carriers is known and may be readily selected by one of skill in the art.

Also provided is the delivery of a metered dose in one or more actuations.

In another embodiment, the compositions may be administered by a sustained delivery device. “Sustained delivery” as used herein refers to delivery of a compound of formulae (I-III) which is delayed or otherwise controlled. Those of skill in the art know suitable sustained delivery devices. For use in such sustained delivery devices, the compound of formulae (I-III) is formulated as described herein.

In addition to the components described above for use in the composition and the compound of formulae (I-III), the compositions and kits described herein may contain one or more medications or therapeutic agents. In one embodiment, the compositions and kits described herein may contain one or more medications or therapeutic agents which are used to treat cancers, including, e.g., cancers characterized by tumors, including solid tumors, and “liquid” or non-solid tumor cancers (e.g., lymphoma). In one embodiment, the medication is a chemotherapeutic. Examples of chemotherapeutics include those recited in the “Physician's Desk Reference”, 64^(th) Edition, Thomson Reuters, 2010, which is hereby incorporated by reference. Therapeutically effective amounts of the additional medication(s) or therapeutic agents are well known to those skilled in the art. However, it is well within the attending physician to determine the amount of other medication to be delivered.

The compounds of formulae (I-III) and/or other medication(s) or therapeutic agent(s) may be administered in a single composition. However, the present invention is not so limited. In other embodiments, the compounds of formulae (I-III) may be administered in one or more separate formulations from other compounds of formulae (I-III), chemotherapeutic agents, or other agents as is desired.

Also provided herein are kits or packages of pharmaceutical formulations containing the compounds of formulae (I-III) or compositions described herein. The kits may be organized to indicate a single formulation or combination of formulations to be taken at each desired time.

Suitably, the kit contains packaging or a container with the compound of formulae (I-III) formulated for the desired delivery route. Suitably, the kit contains instructions on dosing and an insert regarding the active agent. Optionally, the kit may further contain instructions for monitoring circulating levels of product and materials for performing such assays including, e.g., reagents, well plates, containers, markers or labels, and the like. Such kits are readily packaged in a manner suitable for treatment of a desired indication. For example, the kit may also contain instructions for use of a spray pump or other delivery device. Other suitable components to include in such kits will be readily apparent to one of skill in the art, taking into consideration the desired indication and the delivery route.

The compounds of formulae (I-III) or compositions described herein can be a single dose or for continuous or periodic discontinuous administration. For continuous administration, a package or kit can include the compound of formulae (I-III) in each dosage unit (e.g., solution, lotion, tablet, pill, or other unit described above or utilized in drug delivery), and optionally instructions for administering the doses daily, weekly, or monthly, for a predetermined length of time or as prescribed. When the compound of formulae (I-III) is to be delivered periodically in a discontinuous fashion, a package or kit can include placebos during periods when the compound of formulae (I-III) is not delivered. When varying concentrations of a composition, of the components of the composition, or the relative ratios of the compounds of formulae (I-III) or agents within a composition over time is desired, a package or kit may contain a sequence of dosage units which provide the desired variability.

A number of packages or kits are known in the art for dispensing pharmaceutical agents for periodic oral use. In one embodiment, the package has indicators for each period. In another embodiment, the package is a labeled blister package, dial dispenser package, or bottle.

The packaging means of a kit may itself be geared for administration, such as an inhalant, syringe, pipette, eye dropper, or other such apparatus, from which the formulation may be applied to an affected area of the body, such as the lungs, injected into a subject, or even applied to and mixed with the other components of the kit.

The compositions of these kits also may be provided in dried or lyophilized forms. When reagents or components are provided as a dried form, reconstitution generally is by the addition of a suitable solvent. It is envisioned that the solvent also may be provided in another package.

The kits of the present invention also will typically include a means for containing the vials in close confinement for commercial sale such as, e.g., injection or blow-molded plastic containers into which the desired vials are retained. Irrespective of the number or type of packages and as discussed above, the kits also may include, or be packaged with a separate instrument for assisting with the injection/administration or placement of the composition within the body of an animal. Such an instrument may be an inhalant, syringe, pipette, forceps, measuring spoon, eye dropper or any such medically approved delivery means.

In one embodiment, a kit is provided and contains a compound of formulae (I-III). The compound of formulae (I-III) may be in the presence or absence of one or more of the carriers or excipients described above.

In a further embodiment, a kit is provided and contains a compound of formulae (I-III) in a second dosage unit, and one or more of the carriers or excipients described above in a third dosage unit. The kit may optionally contain instructions for administering the medication and the compound of formulae (I-III) to a subject having a disease characterized by the dysregulation of the RAS/RAF/MEK/ERK pathway.

The compounds described herein are useful in regulating conditions which are associated with the RAS/RAF/MEK/ERK pathways. In one embodiment, such a disease is associated with abnormal cellular proliferation. The term “abnormal cellular proliferation” refers to the uncontrolled growth of cells which are naturally present in a mammalian body. In one embodiment, a disease which is characterized by abnormal cellular proliferation is cancer, including, without limitation, cancer of the prostate, head, neck, eye, mouth, throat, esophagus, bronchus, larynx, pharynx, chest, bone, lung, colon, rectum, stomach, bladder, uterus, cervix, breast, ovaries, vagina, testicles, skin, thyroid, blood, lymph nodes, kidney, liver, intestines, pancreas, brain, central nervous system, adrenal gland, skin or a leukemia or lymphoma. In one embodiment, the disease characterized by abnormal cellular proliferation is melanoma skin cancer or cancer of the lung, colon, breast or prostate. In another embodiment, the abnormal cellular proliferation is associated with either solid tumor or hematological cancer.

The term “regulation” or variations thereof as used herein refers to the ability of a compound of formulae (I-III) to inhibit one or more components of a biological pathway. In one embodiment, “regulation” refers to inhibition ERK1/2 activity. In yet another embodiment, regulation includes inhibition of the RAS/RAF/MEK/ERK pathway.

The activity of compounds of formulae (I-III) was established in multiple in vitro and in vivo assays. For example, compounds of the invention were demonstrated to cause inhibition of ERK1 and ERK2 enzymatic activities in biochemical assays using a homogeneous time resolved fluorescence (HTRF) technique; representative data are provided in Table 2. Furthermore, compounds of the invention were found to be active in a cell-based mechanistic assay; that is, compounds of the invention were demonstrated to inhibit phosphorylation of RSK1(S380) (the downstream protein target of ERK1/2) by an enzyme-linked immunosorbent assay (ELISA) method. Representative data are provided in Table 2. The functional utility of compounds of formulae (I-III) was demonstrated by their activity in in vitro tumor cell proliferation assays in a panel of tumor cell lines with mutations in the RAS/BRAF/MEK/ERK pathway; representative data are again provided in Table 2. The compounds of formulae (I-III) exhibit ERK1/2 inhibitory activity, and therefore can be utilized in order to inhibit abnormal cell growth in which the RAS/RAF/MEK/ERK pathway plays a role. Thus, the compounds of formulae (I-III) are effective in the treatment of disorders with which abnormal cell growth actions of RAS/RAF/MEK/ERK dysregulation are associated, such as cancer. One of skill in the art would recognize that there is an established link between activity in tumor cell proliferation assays in vitro and anti-tumor activity in the clinical setting. For example, the therapeutic utility of a variety of pharmaceutical agents, e.g, taxol (Silvestrini, Stem Cells, 1993, 11(6):528-535), taxotere (Bissery, Anti Cancer Drugs, 1995, 6(3):330) and topoisomerase inhibitors (Edelman, Cancer Chemother. Pharmacol., 1996, 37(5):385-39), has been demonstrated by using in vitro tumor proliferation assays.

Finally, compounds of formulae (I-III) were demonstrated to inhibit in vivo tumor growth upon dosing the compounds in human tumor xenograft models, such as the A375 human melanoma xenograft model harboring B-RAF V600E mutation, the HT-29 human colon cancer xenograft model harboring B-RAF V600E mutation, the HCT116 human colon cancer xenograft model harboring KRAS mutation, the A549 human lung carcinoma xenograft model harboring KRAS mutation, and the BxPC3 human pancreatic carcinoma xenograft model. The compounds were also demonstrated to inhibit the level of phospho-RSK in the tumors in the A375 xenograft model, upon treatment with compounds; this indicates effective inhibition of the target proteins ERK1/2 in vivo by compounds of the invention. One of skill in the art would recognize that there is an established link between activity in human tumor xenograft models and anti-tumor activity in the clinical setting.

Compounds of formulae (I-III) that have particularly promising utility can be identified by using the assays as described herein. For example, compounds of formulae (I-III) that are found to exhibit IC₅₀ values less than 100 nM in the ERK1/2 biochemical assays, and IC₅₀ values less than 500 nM in the phospho-RSK1 and cell proliferation assays, and causing 40% or greater tumor growth inhibition in one or more human tumor xenograft models, would be identified as particularly useful compounds of the invention.

In one embodiment, methods for regulating the RAS/RAF/MEK/ERK pathway are provided and include administering a therapeutically effective amount of a compound of formulae (I-III) to a patient in need thereof.

In a further embodiment, methods for inhibiting ERK1/2 are provided and include administering a therapeutically effective amount of a compound of formulae (I-III) to a patient in need thereof.

In another desirable embodiment, methods for treating a disease characterized by an abnormal cellular growth resulting from a dysregulated RAS/RAF/MEK/ERK pathway are provided and include administering of a therapeutically effective amount of a compound of formulae (I-III) to a patient in need thereof.

In a further desirable embodiment, methods for treating a condition treatable by inhibiting ERK1/2 are provided and include administering a therapeutically effective amount of a compound of formulae (I-III) to a patient in need thereof.

As described herein, “a therapeutically effective amount” of a compound when used for the treatment of a condition is an amount that at least slows the progression of the condition. “A therapeutically effective amount” of a compound when used for the treatment of cancer is an amount which may slow the progression of cancer, reduce the number of cancer cells in fluids (e.g., blood, peripheral cells or lymphatic fluids), reduce tumor size, inhibit metastasis, inhibit tumor growth and/or ameliorate one or more of the symptoms of the cancer. For cancer therapy, efficacy can be measured for example, by assessing the time to disease progression and/or determining the response rate.

Process for Preparing the Compounds

Methods useful for preparing the compounds of formulae (I-III) are set forth in the Examples and generalized in the Schemes below. One of skill in the art will recognize that the schemes can be adapted to produce other compounds and their pharmaceutically acceptable salts, prodrugs, solvates, hydrates, or stereoisomers of formulae (I-III).

In the following reactions described to prepare compounds described herein, it can be necessary to protect reactive functional groups, for example hydroxyl, amino, imino, thio or carboxyl groups, which are desired in the final product, to avoid their unwanted participation in the reactions.

In one embodiment, a 4-nitropyrazole [A] is reacted with a 2,4-dichloropyrimidine [B] to provide a pyrazolyl-pyrimidine [C]. This reaction is performed in the presence of a base, such as potassium carbonate, in a suitable solvent such as acetone or dioxane. The reaction may be performed at elevated temperatures up to the reflux temperature of the solvent. Intermediate [C] is then reacted with an amine R⁴—NH₂ to provide the intermediate [D]. This coupling reaction may be performed in the presence of a palladium catalyst such as Pd₂(dba)₃ [tris(dibenzylideneacetone)dipalladium(0)], BINAP (2,2′-bis(diphenylphosphino)-1,1′-binaphthyl), and potassium carbonate, in a suitable solvent such as dioxane. The reaction may be performed at elevated temperatures, for example in dioxane at 90° C. in a sealed glass tube. Reduction of the nitro moiety in [D] then provides the amino-pyrazolyl intermediate [E]. This reduction process can be carried out by reaction with zinc powder and ammonium chloride in a solvent such as THF:methanol (2:1), at a temperature such as 0° C. to 25° C. The amine intermediate [E] is then reacted with an amine [F] to form a compound of the invention, namely the urea (I-A). This coupling reaction can be performed using CDI (1,1′-carbonyldiimidazole) in a solvent such as THF. The reaction may be performed at elevated temperatures, for example in THF at 85° C. to 120° C. with microwave radiation. This coupling reaction can also be carried out by using 4-nitrophenyl chloroformate, pyridine and DIPEA (diisopropylethylamine) instead of CDI.

In this method, intermediate [C] is prepared as described in Scheme 1, and then a reduction process is carried out to provide amino-pyrazole [G]. This reduction process can be carried out by reaction with zinc powder and ammonium chloride in a solvent such as THF:methanol (2:1), at a temperature such as 0° C. to 25° C. The amine intermediate [G] is then reacted with an amine [F] to form a urea intermediate [H]. This reaction can be carried out by using 4-nitrophenyl chloroformate, pyridine and DIPEA (diisopropylethylamine) in a suitable solvent such as DCM (dichloromethane), at a temperature such as 0° C. to 25° C.

The reaction may be performed at elevated temperatures, for example in dioxane at 90° C. in a sealed glass tube. An alternative method for the last step is to react the intermediate [H] with an amine R⁴—NH₂ in ethanol or isopropanol, optionally in the presence of DIPEA, with heating in a sealed glass tube.

In this method, a 2,4-dichloropyrimidine or 2-chloro-4-bromopyrimidine [B] is reacted with a heterocyclic ester [J] to form the intermediate [K]. The reaction can be carried out in the presence of a base, for example potassium carbonate, in a suitable solvent such as acetonitrile. The reaction may be performed at elevated temperatures up to the reflux temperature of the solvent. The intermediate [K] is then reacted with an amine R⁴—NH₂ to provide the intermediate [L]. This coupling reaction may be performed in the presence of a palladium catalyst such as Pd₂(dba)₃, BINAP, and potassium carbonate, in a suitable solvent such as dioxane. The reaction may be performed at elevated temperatures, for example in dioxane at 90° C. to 100° C. in a sealed glass tube. An alternative method to form the intermediate [L] is to react the intermediate [K] with an amine R⁴—NH₂ in ethanol or isopropanol, optionally in the presence of DIPEA, with heating in a sealed glass tube. The ester moiety in intermediate [L] is hydrolyzed to provide the corresponding carboxylic acid [M], for example by treatment with aqueous sodium hydroxide or aqueous lithium hydroxide in a solvent such as methanol or THF, at a temperature such as 0° C. to 50° C. The intermediate [M] is then coupled with an amine [F] to form a compound of the invention, namely the amide (I-B). This amide-coupling reaction can be carried out by using the amide-coupling reagent EDC [1-ethyl-3-(3-dimethylaminopropyl)carbodiimide], optionally in the presence of HOBt (1-hydroxy-benzotriazole) and triethylamine, in a suitable solvent such as NMP (N-methyl-2-pyrrolidone). The reaction may be performed at a temperature such as 0° C. to 25° C. This coupling reaction can alternatively be carried out by using any of several other amide-coupling reagents that are known to those skilled in the art, for example T3P (propylphosphonic anhydride).

Scheme 3a depicts a variation of Scheme 3, wherein the amide-coupling reaction with amine [F] is carried out first, followed by reaction with the pyrimidine [B], and then reaction with the amine R⁴—NH₂ to provide a compound of the invention, namely the amide (I-B).

Scheme 4 depicts a synthesis method to prepare compounds of formula (I) where M is a bond, R²═CH₂NH₂, Z═N, and X═CR⁷. In this method, a 2,4-dichloropyrimidine or 2-chloro-4-bromopyrimidine [B] is coupled with a heterocyclic ester [N] to form the intermediate [O], by a method similar to that described in Scheme 3 for the preparation of [K].

Hydrolysis of the ester moiety in [P] to form the corresponding carboxylic acid [Q] is achieved by methods similar to those described in Scheme 3 for the preparation of [M]. The intermediate [Q] is then coupled with an amine [R] to form the amide [S], by using amide-coupling methods such as those described for the preparation of (I-B) in Scheme 3. As an alternative, the ester intermediate [P] can be converted directly to (S) by reaction with an amine [R], in the presence of trimethylaluminum in a suitable solvent such as toluene. The reaction is carried out at a temperature such as 0° C. to 100° C., optionally using microwave radiation. Reduction of the nitrile moiety in [S] is carried out to provide the corresponding amine (I-C), a compound of the invention, by hydrogenation using Raney nickel in methanolic ammonia.

In this method, a 2-amino-4-bromopyridine [Y] is reacted with an iodo compound R⁴—I in the presence of a palladium(0) catalyst, to provide the pyridine intermediate [Z].

In this method, a 2-chloro-pyridine [AD] is oxidized, nitrated and then reacted with an amine R⁴—NH₂ to provide the 4-nitro-pyridine N-oxide intermediate [AG]. The N-oxide and nitro moieties in [AG] are reduced and the resulting 4-amino group in [AH] is converted to a bromide moiety. The 4-bromo-pyridine intermediate [AI] is then reacted with an appropriate heterocycle such as the pyrrole derivative [AJ], to provide a compound of the invention (I-G).

The reaction may be performed at elevated temperatures, for example in dioxane at 90° C. in a sealed glass tube, or using microwave radiation at 100° C. The ester moiety of intermediate [AV] is then hydrolyzed to provide the corresponding carboxylic acid [AW], for example by treatment with aqueous sodium hydroxide or aqueous lithium hydroxide in a solvent such as methanol or THF, at a temperature such as 0° C. to 50° C. The carboxylic acid [AW] is then coupled with an amine [R] to form the amide [AX], by using amide-coupling methods such as those described for the preparation of (I-B) in Scheme 3. Reduction of the nitrile moiety in [AX] is carried out to provide the corresponding amine (I-K), a compound of the invention, by hydrogenation using Raney nickel in methanolic ammonia.

In this method, a 2,4-dichloro-pyridine (or 2-chloro-4-bromopyridine) [AT] is reacted with sodium azide to provide the 4-azido-pyridine [AY], which is then condensed with methyl propiolate to produce the triazole intermediate [AZ]. The ester moiety in intermediate [AZ] is hydrolyzed by methods such as those described in Scheme 11 to give the corresponding carboxylic acid, which is then reacted with an amine such as [F] by using amide-coupling methods such as described in Scheme 10, or reacted with an amine such as [R] by using amide-coupling methods and then reduced such as described in Scheme 11, to provide a compound of the invention (I-L).

The reaction is carried out in a suitable solvent such as DMF or NMP, and may be performed at elevated temperatures, for example at 90° C. to 100° C. in a sealed glass tube.

Scheme 20 depicts a further method for the preparation of compounds of formula (I), where in this example M is a bond, R²═CH₂NH₂, Z═N, and X═CR⁷. This method provides an alternative to the method described in Scheme 4. In this method, an amino-alcohol (in this example, a single enantiomer) [BD] is converted by standard methods to the N-Boc protected analog [BE], and then the hydroxyl moiety is converted to the corresponding methanesulfonate ester, for example by reaction with methanesulfonyl chloride and triethylamine in a solvent such as dichloromethane. This methanesulfonate compound [BF] is then reacted with sodium azide to form the corresponding azide derivative [BG]. The azide reaction is carried out in a suitable solvent such as DMF or NMP, and may be performed at elevated temperatures, for example at about 50° C. The N-Boc group is then removed by standard methods, for example by treatment with 4 M HCl in dioxane. The resulting amino azide compound [BH] is then coupled with intermediate [Q] to form the amide [BI], by using amide-coupling methods such as those described for the preparation of (I-B) in Scheme 3. The azide moiety is reduced, for example by reaction with zinc dust and ammonium chloride in a solvent such as methanol, to provide a compound of the invention (I-P), in this example as a single enantiomer.

Example 34 Biological Assays

ERK1 and ERK2 HTRF (Biochemical) Assays

These assays employed a homogeneous time resolved fluorescence (HTRF) technique. The compounds were serially diluted by half-log with concentrations ranging from 0.0005 to 10 uM in the assay buffer (50 mM Tris pH=7.5, 1 mM EGTA, 2 mM DTT, 10 mM MgCl₂, 0.1% Tween-20) and 20 uL of substrate-ATP mix [1 uM Biotin—LC—Myelin Basic Protein (MBP) derivatized Peptide (Anaspec)-24 uM ATP (Sigma)] was added to each well of the assay plate. Then 10 uL of enzyme mix [25 nM ERK1 or ERK2 (Jubilant Biosys) in assay buffer] was added to each well. The plate was incubated at room temperature for 60 min with shaking. The HTRF mix [625 nM LANCE® Ultra Europium-anti-phospho-MBP (Perkin Elmer) and 2 nM Phycolink® Streptavidin-Allophycocyanin (SA-APC) (Prozyme) in HTRF buffer (50 mM Tris-HCl pH=7.5, 100 mM NaCl, 0.1% BSA, 0.05% Tween20, 0.5 mM EDTA)] was prepared and 75 uL of this mix was added to the HTRF plate. After incubation for 60 min at room temperature, 10 uL of the reaction mixture was transferred to the HTRF assay plate and incubated for 45 min at room temperature with shaking. Plate was read using Pherastar in HTRF mode (excitation 337 nm, emission 665 & 620 nm). The IC₅₀ values (half maximal inhibitory concentration values) were subsequently determined using a sigmoidal dose-response curve (variable slope) in GraphPad Prism® 5 software. Compounds of the invention caused inhibition of ERK1 and ERK2 as determined in these assays. Representative data are provided in Table 2.

Cell Proliferation (Alamar Blue) Assay

HT-29 (colorectal carcinoma, B-RafV600E), HCT116 (colorectal carcinoma, K Ras G13D), A375 (melanoma, B-RafV600E) and SK-Me12 (melanoma, NRAS Q61R) cells (obtained from ATCC, USA) were seeded (5000 cells/well) in 96-well tissue culture plate and incubated at 37° C./5% CO2 for 16-24 hours. The cells were then treated with compounds, at concentrations typically from 0.0005 to 10 uM prepared in 3-fold serial dilutions. The plates were then incubated for 72 h at 37° C./5% CO₂ in a moist environment. Then Alamar Blue™ reagent (final concentration 1×) was added to each well and incubated for 1-3 h at 37° C./5% CO₂. The plates were read on fluorescence reader at 540 nm excitation and 590 nm emission wavelengths. The IC₅₀ values were subsequently determined using a sigmoidal dose-response curve (variable slope) using GraphPad Prism® 5 software. Compounds of the invention caused inhibition of HT-29, HCT116, A375 and SK-Me12 cell proliferation as determined in these assays. Representative data for the HT-29 and HCT116 cell proliferation assays are provided in Table 2.

Phospho-RSK1(S380) ELISA Assay

HT-29 cells (colorectal carcinoma, B-RafV600E); obtained from ATCC, USA) were seeded (60,000 cells/well) in a 96-well plate and incubated at 37° C./5% CO₂ overnight and then treated with desired compound dilutions for 2 h. Medium was removed and cells were rinsed once with ice-cold 1×PBS, then 0.070 mL ice-cold 1× cell lysis buffer containing 1 mM PMSF was added to each well and the plate was incubated on a shaker for 2 h and 30 min at 4° C. The plate was then centrifuged for 20 min (×4000 rpm) at 4° C. and the supernatant was transferred to a new plate. Cell lysates were diluted with sample diluent at a ratio of 1:1. The ELISA was then carried out following the manufacturer's protocol (PathScan® phospho-RSK1(Ser380) Sandwich ELISA Kit, Cell Signaling Technologies). The plate was read at 450 nm within 30 min after adding STOP solution. The IC₅₀ values were subsequently determined using a sigmoidal dose-response curve (variable slope) in GraphPad Prism® 5 software. Compounds of the invention inhibited phosphorylation of RSK1(5380) (the downstream target of ERK1/2) as determined in this assay. Representative data are provided in Table 2.

In Vivo Studies in Tumor Xenograft Models

Tumor Cell Implantation and Randomization of Animals

Foxn1 nu/nu strain of female mice (obtained from Charles River Laboratories, USA), 8-10 weeks of age, body weight range 23-25 g, were used for the tumor xenograft efficacy studies. Human cancer cell lines (such as melanoma A375, colorectal HT29, pancreatic BxPC3, colorectal HCT116, and lung A549) were first grown in vitro, and then about five million (5×10⁶) of these cells in 100 μL of serum free medium were mixed with an equal amount of matrigel, and the entire mixture was injected subcutaneously at the right flank region of mice. The tumors were measured with Vernier calipers periodically after the first week of injection. When the tumor volume reached 120-150 mm³ (about 3-4 weeks after injection) the animals were randomized into different groups so that their tumor volume was approximately the same in all groups.

Determination of In Vivo Efficacy of Tumor Growth Inhibition

For PO dosing, the compounds were prepared in a formulation containing 0.5% Methyl cellulose and 0.01% Tween 80. For IV, SC, or IP dosing, the compounds were prepared in 6% solutol—ethanol (1:1), 6% DMSO and 88% saline. Animals were dosed with compounds prepared in specific formulations via PO, IP or SC route either QD or BID at the required doses. Tumors size and body weights were measured twice or thrice in a week. Tumors were harvested at the end of the study after euthanizing the animals according to approved protocols. From the harvested tumor one part was snap frozen and submitted for PK studies, and the other part was homogenized and the lysates were tested for target inhibition using western blotting. Before the tumor was harvested, blood (˜200 μL) was collected by ocular bleeding for PK studies.

Changes in tumor volume (Δ volumes) for each treated (T) and control (C) group were calculated by subtracting the mean tumor volume on the first day of treatment (starting day) from the mean tumor volume on the specified observation day. These values were used to calculate a percentage growth (% T/C) using the formula: % T/C=(ΔT/ΔC)×100, where ΔT>0, or

-   -   % T/C=(ΔT/ΔTi)×100, where ΔT<0 and Ti is the mean tumor volume         at the start of the experiment.         Percentage tumor growth inhibition was calculated as [100−%         T/C]. Percentage body weight change was calculated as [(Body         weight on specified observation day—Body weight on starting         day)/Body weight on starting day]×100.         Results

Compounds of the invention were active in these in vivo tumor xenograft studies. For example, in a human melanoma xenograft model (A375) harboring B-RAF V600E mutation, compounds of Example 201 and Example 211 caused approximately 70 to 76% tumor growth inhibition when dosed orally at 50 mg/kg BID for 17 days. There was no significant body weight loss observed at this dose for either compound. In a pharmacodynamic assay, compounds of Example 201 and Example 211 caused inhibition of phospho-RSK (the downstream target of ERK1/2) by about 66 and 84%, respectively, as measured in A375 tumor samples harvested at 1 h after dosing at 50 mg/kg PO, when compared to the vehicle control. Also, in this same model (A375), compounds of Example 255, Example 225a, and Example 259 caused approximately 70 to 90% tumor growth inhibition when dosed orally at 50 mg/kg BID for 19 days. There was no significant body weight loss observed at this dose for either compound.

In a human colon cancer xenograft model (HT-29) harboring B-RAF V600E mutation, the compound of Example 201 caused approximately 50% tumor growth inhibition when dosed orally at 50 mg/kg BID for 20 days. There was no significant body weight loss observed at this dose in this study.

In a human pancreatic carcinoma xenograft model, BxPC3 (wild type KRAS), the compound of Example 201 caused about 63% tumor growth inhibition when dosed orally at 50 mg/kg BID for 25 days. There was no significant body weight loss observed at this dose in this study.

In a human colon cancer xenograft model (HCT116; harboring KRAS mutation), the compounds of Example 259, Example 225a, and Example 275 caused approximately 90-100% tumor growth inhibition when dosed orally at 50 mg/kg BID for 24 days. There was no significant body weight loss observed at this dose in this study.

In a human lung carcinoma xenograft model (A549; harboring KRAS mutation), the compound of Example 304, Example 302 and Example 300 caused about 65 to 82% tumor growth inhibition when dosed orally at 50 mg/kg BID for 20 days. There was no significant body weight loss observed at this dose in this study.
